Dent below derailer Hanger

My wife recently bought a new Trek 2000 WSD (2003 year model) and I was looking at the chain ring when the bike was not shifting correctly.

I noticed that there is a dent in the tube just below the derailer hanger (Clamp on) It looks like it may have been designed to be there, but I am not sure.

It does not look like the derailer is hitting it because the paint is so well in tact. Even then, could a derailer snapping into the bottom chain ring actually dent the frame?

I guess this long winded ramble is to ask if this "dent" is normal. My Specialized does not have it, so I have nothing to compare to.

I will be taking her bike in tomorrow to get adjusted, but wanted to know if the frame should have that indention there.

I assume this is something that should be fixed under warranty if it is not right? The bike is only about 8 days old. She has not been off the trainer with it, and there is no way that point could have been hit anyways.

This 'dent' is on the seat tube, right below the front derailleur clamp? If that's so, there's no reason for it to be there. Now, you're not talking about the large dimple on the chainstay, I assume...

Will Trek likely tak care of this under warranty since it is so new?
(Picked it up last Monday....never been off the trainer)

Seems like this would affect the integrity of the frame...its not a dimple, more of a dent. Maybe like the derailer got mashed into it in transit. (Unless a misadjusted derailer can have enough force to dent the frame.)

What would you do if they offered you a % off for the dent, what would be fair. (Assuming it would not affect the integrity of the frame)

I am a bit irked with the shop, I checked everything on delivery, wheels, handlebars, etc. Never thought to look behind the derailer. Only reason I noticed it was because the derailer adjustment went out (for the second time in 4 days) and I saw the dent.
